What you need

Chits of paper, one per player: one marked W (winker), the rest blank. Chairs in a circle.

How to play

Choose a detective, who leaves the room or closes their eyes.
Every other player draws a chit. The one who gets W is the winker. Nobody tells.
The detective returns and stands in the centre of the circle. Players look around at one another quietly.
The winker winks at one player at a time, choosing moments when the detective is looking elsewhere.
A player who is winked at counts silently to five, then "falls asleep": slumps, snores, or slides down the chair with as much drama as they like. They are out and may not hint.
The detective has three guesses to name the winker.

The detective wins by naming the winker within three guesses. The winker wins by putting half the circle to sleep first.

No detective: any player who suspects the winker may raise a hand and accuse; a wrong accusation puts the accuser to sleep.
Two winkers in a big group.
For players who cannot wink, the signal can be sticking out the tip of the tongue.

Describe the game as putting people to sleep; that keeps it right for every age. Seat players so that everyone can see every face.

The detective guesses wildly at once. Each wrong guess must be followed by thirty seconds of watching.
Players stare at the winker and give them away. Tell everyone to keep their eyes moving round the circle.

Time the round with the party timer, make chits or random teams with the chit maker, and keep the points on the scoreboard.
